摘要
为了提高单个传感器故障情况下船舶柴油发电机组转速的稳定性,运用基于State Flow的模糊PID容错控制策略研究了船舶柴油发电机组传感器故障后的转速控制。研究中建立了基于Matlab的传感器故障模拟模型,基于StateFlow的故障判别方法,通过对故障传感器的估算和模糊PID控制,实现了对传感器故障后船舶柴油发电机组的转速控制。仿真结果验证了故障模型的正确性和基于StateFlow的模糊PID控制方法对传感器故障后船舶柴油发电机组转速控制的有效性。上述建模与控制的研究为进行多个传感器故障的容错控制研究奠定了基础。
In order to improve the speed stability of a marine diesel generator set subject to a single sensor fault, this study focused on the generator set＇ s speed control using the StateFlow based fuzzy fault-tolerant PID control strate- gy. In the study, a Matlab-based sensor fault simulation model was developed, and based on the StateFlow indenti- fication for faults, the speed control of the diesel generator set in a sensor fault was realized through fault sensor es- timation and fuzzy PID control. The simulation results verify the correctness of the fault model and show the effec- tiveness of the fuzzy PID based on StateFlow in speed control for the diesel generator set in a sensor fault. The study lays the foundation for the study of fault tolerant control under multiple sensor faults.
